some of which can cause problems for humans‚ plants‚ and animals. There are several main types of pollution and well-known effects of pollution which are commonly discussed. These include smog‚ acid rain‚ the greenhouse effect‚ and "holes" in the ozone layer. Each of these problems has serious implications for our health and well-being as well as for the whole environment. One type of air pollution is the release of particles into the air

Dasean Matheson 11/25/13 APES Ms. Sarameinto Population is the largest increasing factor in our world. This factor is the cause of many events in our world. Poverty hunger and war are just some of the immediate effects of increasing population. Among these extreme causes the less immediate events will be seen with air pollution‚ land degradation‚ which is the effect that’ll have the longest term effect on the world. But how can these events are avoided? Is there any hope of stopping this

particles from coal combustion and‚ in more recent decades‚ motor vehicles have produced severe loss of air quality and significant health effects. 6. Finally‚ emissions of carbon dioxide and other radiatively active gases‚ together with stratospheric ozone depletion‚ represent planet-scale assaults on the quality of our atmospheric environment. 7.

than a dozen volatile organic compounds‚ some of which are known carcinogens; nitrogen oxides; sulfur oxides; and particulate matter‚ tiny particles of solids‚ such as metal and soot. Other emissions that affect human health and create smog include ozone and carbon monoxide. (See Reference 1) The good news is that despite the increase of vehicles on the road‚ air quality today is actually better than it was in the 1970s‚ thanks to the 1970 Clean Air Act. In fact‚ lead emissions from cars have been

Stratospheric ozone depletion (contributed to air pollution) has long been recognized as a threat to human health as well as to the Earth’s ecosystems. Causes Of Air Pollution: | * a) Ozone - A gas that can be found in two places. Near the ground (the troposphere)‚ it is a major part of smog. The harmful ozone in the lower atmosphere should not be confused with the protective layer of ozone in the upper atmosphere (stratosphere)‚ which screens out harmful ultraviolet rays. Sources: Ozone is not

The atmosphere is the complex dynamic natural gaseous system that is essential to support life on planet Earth.
